The Role of Neopterin and Interleukin-6 Detection in Saliva and Plasma in Oral and Oropharyngeal Cancer Patients: A Prospective Study.
Article in Clinical and experimental dental research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThe incidence of oral and oropharyngeal cancer is continually rising and affects increasingly younger patients. Consequently, many studies focus on early diagnosis using appropriate biomarkers. Neopterin and interleukin-6 (IL-6) are promising predictive and prognostic markers of immune response activation, both systemic and local, due to the anatomical proximity of malignancies to the salivary glands. MATERIAL AND
methodsWe collected oral fluid samples from 50 patients before and after the surgical resection of squamous cell carcinoma of the oral cavity and oropharynx. Additionally, blood samples were withdrawn from 20 of these patients and levels of neopterin and IL-6 were estimated using ELISA commercial kits. All gathered data were subsequently statistically analyzed for evaluation and compared to values from a control group of healthy individuals.
resultsIn patients with oral squamous cell carcinoma (OSCC) and oropharyngeal squamous cell carcinoma (OPSCC), there was a significant decrease in neopterin and IL-6 levels in saliva following the surgical removal of the malignancy. These postoperative levels approached those of the control group. There was no significant decrease in neopterin and IL-6 levels in plasma.
conclusionDetection of neopterin and IL-6 in saliva is a reliable diagnostic method for early detection of OSCC and its recurrence, as well as for monitoring therapeutic success, compared to plasma. Neopterin and IL-6 appear to be promising prognostic and predictive markers of the disease.
